General description

α-Cyano-4-hydroxycinnamic acid is the commonly used matrix for analyzing peptides by matrix-assisted laser desorption/ionization mass spectrometry. It inhibits the monophenolase activity and diphenolase activity of mushroom tyrosinase.

Application

α-Cyano-4-hydroxycinnamic acid (CHC) was used in encapsulation of CHC into NaY zeolite. It was used as matrix to investigate the activity of the paclitaxel derivatives using several well-established in vitro angiogenesis assays.
